I was looking on swell lexus' webpage and found this..

Interesting... does anyone have this?

 

you probably need a push start type starter to begin with to use that button. it does look cool though. but, again wishful thinking since some people seem to think that its ok that lexus hasnt added a push start system to the RX, even though every other car in its lineup already has it or some form of it.

 

I have the push button ignition on my new BMW and, other than "cool" factor, I can take it or leave it. I doubt that there is any engineering benefit to it and I would venture a guess that it is more complicated than a standard ignition lock/switch.

probably not too complicated. All you would need to do is run wires to create a short and pull the 'start' wire high. This of course would require a key in the ignition and with the key in the 'on' position, you press the button to start the cranking.

Cool, but not practical. This of course would not be as convenient because if you already have the key in the ignition, you might as well turn it one click over to start up the engine instead of pressing the button.

The reason you need the key there is because your key has an RF tag with a specific frequency that needs to be near the ignition in order to start.

 

I agree with Grumps...I had the push button in a 07 Camry and do not miss that feature at all in my 08 RX....I like having a key....I guess i am old school........

 

Push button start mentality is still debatable....nice to try...but once you got it, you got it. Wish 2 options given....trad key and a push button.....like the AWD drive button? ON-OFF.

 

HAHa...I love the red TRD starter. IMO it looks cool. I asked a similar question a few months ago.

One of my cars has a push, one doesn't...my next, will have it also.
Can't stand juggling my keys in and out of my pockets, for what reason?

 

You still have to carry the key fob that activates the starter. For instance, we all know how little a key is, except the new style keys like we have with Lexus. My BMW key fob is HUGE by comparison, easily twice as big as the Lexus key.

BMW makes two types of key fobs, btw. One you can leave in your pocket and is truly a remote; the other fits in a receptacle. In addition, where do you carry your house key? My key chain is actually bigger with the remote start fob attached than if I had an actual key.

 

Looks cool. Does it come with designer colors to match our interiors? The red's a little too much like an eject button.

 

i dunno how many times ive had my hands full and need to fumble for my key then press the unlock button. now if the car had a keyless system it would make thing easier, like the system on the GS, LS, IS, etc.

 

I have the push button start on my other, no big deal in my opinion. I can take it or leave. Its so much more sensors in the car now and it has its own ECU, more stuff that can fail if you ask me.

 

Got that right. Replacing mechanical actuation is tricky. Doable but take time to establish reliability studies.

 

With the push button start, there are 7 more sensors on the car to detect the fob, plus one computer just for that system and 4 more push buttons on the doors.

 

Works very well on our IS and it's nice to be able to just approach the car and climb in wihout fumbling for keys/buttons. Also our "puddle lights" on the outside mirrors go on when we're close to our IS, which is a nice aide when it's dark out. In general, I like the keyless system, and Lexus seems to have gotten it right. I for one look forward to having this system on the next RX. Just hope that there will be some way to have the fob handle more than one car.
